O1-6 Objectively measured physical activity levels and association with BMI z-score among children and adolescents in Morocco

Abstract Background Physical activity is associated with improved psychological well-being and lower levels of cardio metabolic risk factors, diabetes, obesity among children and adolescent. The purpose of the study was 1- to examine gender, type of day, and age grade differences in objectively PA; 2- to examine the attainment of recommended physical activity guidelines; 3-to examine the association between PA levels and BMI z-score among children and adolescents in Morocco. Method 172 Moroccan children/adolescents (mean age = 10.92 ± 1.55 years, mean BMI z-score = -0.16 ± 1.33; 19.2 % overweight) were recruited for this study and wore a tri-axial accelerometer (GT3X+) for 7 consecutive days. Two-way analysis of covariance was used to examine gender and age grade differences in physical activity level separately for weekdays and weekends, adjusted for body mass index for age (BMI z-score) and wear time. Logistic regression analyses were conducted to examine independent relationships between attainments of physical activity guidelines and gender. Pearson correlation was used to assess the association between physical activity levels and BMI z-score. Results In both weekends and weekday, children spent more time in Light physical activity than adolescents (p > 0.001), boys were more engaged in moderate activity (p > 0.001) and vigorous (p > 0.001) activity and took more steps than girls. Boys were eight time more likely to meet the recommendation for at least 60 min of moderate to vigorous physical activity per day than girls (OR: 8.569; 95% [CI]: 4.23-17.32), p > 0.001. Among adolescent, moderate to vigorous PA were inversely correlated with BMI z-score (r = -0,213; p = 0.04). Conclusion The findings can shed light on the need of urgent scaling up of implementation of known effective policies and programmes for adolescents and girls to increase their involvement in PA.

Background
Physical activity is associated with improved psychological well-being and lower levels of cardio metabolic risk factors, diabetes, obesity among children and adolescent. The purpose of the study was 1-to examine gender, type of day, and age grade differences in objectively PA; 2-to examine the attainment of recommended physical activity guidelines; 3-to examine the association between PA levels and BMI z-score among children and adolescents in Morocco. Method 172 Moroccan children/adolescents (mean age = 10.92 AE 1.55 years, mean BMI z-score = -0.16 AE 1.33; 19.2 % overweight) were recruited for this study and wore a tri-axial accelerometer (GT3X+) for 7 consecutive days. Two-way analysis of covariance was used to examine gender and age grade differences in physical activity level separately for weekdays and weekends, adjusted for body mass index for age (BMI zscore) and wear time. Logistic regression analyses were conducted to examine independent relationships between attainments of physical activity guidelines and gender.

Results
In both weekends and weekday, children spent more time in Light physical activity than adolescents (p > 0.001), boys were more engaged in moderate activity (p > 0.001) and vigorous (p > 0.001) activity and took more steps than girls.

Among adolescent, moderate to vigorous PA were inversely correlated with BMI z-score (r = -0,213; p = 0.04).

Conclusion
The findings can shed light on the need of urgent scaling up of implementation of known effective policies and programmes for adolescents and girls to increase their involvement in PA.

Refraining from sport participation has negative effects on mental and physical well-being, which tracks into adulthood. It is therefore important for youth to be facilitated into lifelong active participation in physical activity and sport. Despite the importance of sports injury prevention in youth, no broad scale approaches that work in real-life situations with significant positive effects exist. Sports coaches (SC) and physical educators (PE) experience current approaches exercises as not context specific, time consuming and not contributing to their training goals. This leads to poor uptake, implementation and maintenance of current sports injury prevention exercises. To overcome current barriers, the Move Healthy project develops ICT based video material of routines for and with PE and SC, which supports them to prevent sports injuries in youth. The purpose of this crucial mapping phase is to identify the wishes and needs of the endusers PE and SC regarding injury prevention. Methods A mapping procedure was conducted to identify the wishes and needs of PE and SC regarding integration of injury prevention in their daily work. For that, focus groups, with PE from primary and secondary education and basketball and soccer coaches from 6 EU countries, were held. Results A total of 31 PE (primary and secondary school) and 37 sport coaches (basketball and soccer) from 6 EU countries were included. The qualitative results from SC state that injury preventive routines should focus on: sport performance, good quality of movement, dynamic combinations of existing exercises and it should be fun and challenging. PE tend to focus more on: motivation aspects, how to overcome barriers and implementation aspects. For both groups, a clear and specific explanation about the why, what and how regarding injury prevention based on principles of motor learning should be included in the approach.

Conclusions
The results from the mapping phase will lead to guidelines, statements regarding educational concepts, content and design criteria for video material on the ICT based support platform for SC and PE.
